Hello I have been recently working on a Computer Controlled Robot, everything is more or less working at the moment, But the problem is I have no idea what to do next, I am looking at making a basic object avoidance system, from detecting change in Light levels, from LDR's, but I am stuck at what to do next, I have some wireless modules to make the robot wireless, but I am still in the process of getting them to work.

what model number tx/rx are you using, i suspect you may just have an RF stage. radio is a funny thing, you need to have encoding on the data to make sure you get an even number of 0's and 1's (near even anyhow) otherwise the rx struggles to see the data you are sending above the noise.

there was a project based on open WRT and used a wireless router, camera and robot base to send data back and forth from a pc, however i cant find the link now

I dont know these modules off the top of my head but i would think they are just an RF stage.

So try first with a preamble, a couple of bytes of 101010 etc, still will help the AGC in the RX to balance itself (sent from the TX side obviously ) then deduct that from the RX side in your firmware so you get the data you are looking for.
